Pseudo-total internal reflection fluorescence
Did you know?
A total internal reflection fluorescence microscope (TIRFM) is a type of microscope with which a thin region of a specimen, usually less than 200 nanometers can be observed. TIRFM is an imaging modality which uses the excitation of fluorescent cells in a thin optical specimen section that is supported on a … See more Widefield Fluorescence was introduced in 1910 which was an optical technique that illuminates the entire sample as seen in Figure 1. Confocal microscopy was then introduced in 1960 which decreased the background and … See more There are two common methods for producing the evanescent wave for TIRFM. The first is the prism method which uses a prism to direct the laser toward the interface between the coverglass and the media/cells at an incident angle sufficient to cause total … See more The idea of using total internal reflection to illuminate cells contacting the surface of glass was first described by E.J. Ambrose in 1956. This idea was then extended by Daniel … See more Fundamental Physics behind TIRFM TIRFM is predicated on the optical phenomena of Total Internal Reflection, in which waves arriving at a medium interface do not transmit into medium 2 but are completely reflected back into medium 1. Total … See more In cell and molecular biology, a large number of molecular events in cellular surfaces such as cell adhesion, binding of cells by hormones, secretion of neurotransmitters, … See more The basic components of the TIRFM device include: 1. Excitation Beam Light Source 2. Cover Slip & Immersion oil See more The image is detected by a charged-coupled device (CCD) digital camera. CCD cameras have photon detectors, which are thin silicon wafers, … See more WebAug 1, 2011 · An automatic calibration and angle-scanning prism-type total internal reflection fluorescence microscope (TIRFM) was modified to function in both TIRFM and pseudo-TIRFM modes. When the incident angle of the excitation laser beam was controlled to be larger than the critical angle, the instrument served as a variable-angle TIRFM.
WebAbstract. Total internal reflection fluorescence (TIRF) microscopy provides a means to selectively excite fluorophores in an aqueous or cellular environment that is very near a solid surface (within ≤100 nm: less than one-fifth the thickness of a confocal microscopy section) without exciting fluorescence from regions further from the surface. Web4. Construct a bungee cord composed of two large rubber bands and attach it to the small rubber band around Barbie’s ankles. 5. Let Barbie hang upside down, and measure the distance from the “free” or “loose” end of the bungee (the end NOT around her ankles) to the tip of her head. Measure in centimeters and then convert to meters. This is the initial …
